Hand-held Measuring Head XRS H 21

For hydrogen leak detection using the XRS 9012

Hand-held measuring head XRS H21

The hand-held measuring head XRS H 21 belongs to the standard accessories of the hydrogen leak detector XRS 9012. The actual sensor is located at the tip of the hand-held measuring head, which is connected to the leak detector via a cable. The measuring device responds as soon as trace gas reaches the hand-held measuring head.

The XRS H 21 is perfectly suited for pinpoint leak detection and can also be used in combination with the standard carry handle XRS P 12.
